FREDERICK E. SCHMITS, OF OAKLAND, CALIFORNIAL ICE-CREAM MOLD ANDMEASURE.

SPECIFICATION forming part of Letters Patent No. 626,468, dated June 6,1899.

Application filed July 28,1898. Serial No. 687,066. (N0 model.)

To all], whom it may concern.-

Be it known that I, FREDERICK E. SoHMITs, a citizen of the UnitedStates, residingat Oakland, county of Alameda, State of California, haveinvented an Improvement in Ice-Cream Molds and Measures; and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to a device for measuring and molding icecream,water-ice, and similar condiments and a means whereby the material isloosened and discharged from the in o1d,in combination with a mechanismwhich enables the user to operate the device with one hand.

It also relates to such construction that the measures or molds areinterchangeable with relation to the operating mechanism, so that moldsof different forms and sizes may be employed in conjunction with asingle set of handles.

Referring to the accompanying drawings, Figure 1 is a sectional viewshowing the mechanism. Fig. 2 is a plan View of the same. Fig. 3 showsthe clutch mechanism.

A is the mold and measure, which is here shown conical in shape; but itmay be of any preferred form, so as to produce an ornamental shape tothe material with which it is filled. Upon one side of the mold issecured a lug B, by which itis attached to the operative mechanism to behereinafter described. Through that portion of the lug which extendsover the closed smaller end of the cup or mold is fitted a sleeve 0,which is made of any non'corrosive material, and through this sleevepasses a rectangular rivet or bolt D, the inner end of which passesthrough and is rigidly secured or riveted to the scraper E. This scraperconsists of a plurality of arms d, fitting closely the contour of theinterior of the mold, and by means of the bolt D, to which it isattached, it may be turned around within the mold when the latter hasbeen filled and inverted, so as to detach the contents from the sides ofthe mold and allow the molded substance to be removed from the mold. Theouter end of the rivet or bolt D carries a square or othersuitably-shaped head F, and this head fits into a correspondingly-shapedsocket which is formed in the hub of a pinion G, and this pinion isjournaled and turnable within a frame H. The under surface of this frameH is shaped so as to engage the upper portion of the lug B, which issecured upon the mold A, so that when the two fit together therectangular head F will enter the socket G" of the pinion G.

Ihe frame II is here shown as contained within an exterior casing I, andthis casing and the lug B of the mold have holes made through themcoincident wit-h each other to receive a locking-pin J, which passesthrough the two and holds them together. The pin may be screw-threaded,having a head upon one end and a securing thumb-nut upon the other, sothat it is easily-removed, and when so removed the mold,with itsattached scraperarms and bolt D, can be disengaged and another mold ofdifferent size or shape inserted into the casing I and the frame II.This facilitates the use of molds of difierent sizes and shapes with asingle set of operating-handles. p

The pinion G is engaged by the teeth of a second pinion K, which isjournaled in the frame H in proper relation to the first-named pinion.Upon the same shaft with the pinion K is another pinion L, and this isengaged by a gear M, through which passes the shaft N of the handle 0.As many pinions may be introduced between the scrapers and theoperating-handles as are needed to produce the desired speed at theoption of the maker or user. The handle P is fixed with relation to thecasing I, and the handle 0 is turnable within this casing, carrying thepinion M. A coiled spring Q surrounds the shaft N and has one endconnected with said shaft and the opposite end connected with some fixedpoint, said spring serving to normally press the handle 0 outwardly andaway from the fixed handle P.

When the device is to be operated, the user takes it in his hand, and bypressing upon the handles 0 and P the handle 0 will be drawn toward thehandle P against the tension of the spring Q. This turns the gear M andthrough it acts upon the intermediate pinions and through these turnsthe bolt or rivet D,which carries the scrapers E within the cup or moldA. It is preferable to continue the motion of the scrapers in onedirection. Therefore I employ a clutch which engages with the gear orpinion to which it is attached, so that when the handles .and P arepressed together the engagement of the clutch will cause the gears torevolve and turn the scrapers; but when the pressure upon the handlesisreleased the coiled spring Q moves the handle 0 outwardly, and theclutch or equivalent device being re-.

leased allows the parts connected with the movable handle to turn backfreely without moving the scrapers within the measuringcup. In this waythe scrapers are advanced by each pressure upon the handles and remainstationary while the handles are separated by the action of the springQ.

The form of clutch which I have here shown consists of two arms a,loosely pivoted upon each side of the shaft of the gear or pinion to iwhich they are connected, and the latter being chambered out to receivethese arms the interior may be corrugated or lined with a] soft metal,like copper, and the outer ends of the arms a normally are beveled orsharpened, so that they engage the interior surface I) of the chamberand lock against it when the shaft is turned in one direction; but theymove freely over the surface, so as to allow the shaft to be turned inthe opposite direct-ion without acting upon the pinion.-

The clutch may be connected with either of the gears intermediatebetween the handleshaft and the turnable socket, the object being tomake the movement of the latter continuous in one direction.

By the construction and interlocking of the frames which carry themeasuring-cups and the operative parts by which the scrapers are rotatedany change may be made in the cups to suit the conveniences ornecessities of the occasion.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An ice-cream mold or measure having scrapers pivoted and turnablewithin it, a polygonal stem to which the scrapers are fixed extendingaxially outwardthrough the end of the mold, a pinion the hub of whichhas a socket with which said stem engages, pinions by which thesocket-pinion is turned and a fixed and a movable handle, the latterbeing connected so as to turn the pinions and the scraper when thehandle is moved.

2. An ice-cream mold and measure having scrapers fitting and turnablewithin it, a bolt of, and through the extended end of which the boltpasses, a frame and means whereby it is removably secured in place, apinion re-- movably'engaging said bolt whereby the latter may bedetached with the mold, gearing for operating the pinion and a fixed andmovable handle for operating the gearing, a clutch mechanism'whereby theparts are engaged to turn the scraper-arms when the handles are pressedtogether and released to allow the scraper-arms to remain stationarywhen the handles separate, and a spring acting upon one of the handlesto normally separate it from the other handle.

4:. An ice-cream mold and measure having scrapers fitting and tu rn ablein its interior, a lug fixed to the outside, an independent casingcontaining actuating-pinions and having fixed and-movable handles and alocking device whereby a variety of molds may be fitted to a single setof gearing and handles.

5. In an apparatus of the character described, a mold with scrapersturnable within it, fixed and movable handles and gearing intermediatebetween the handles and the scrapers, and a-clutch mechanismconsistingof arms loosely pivoted upon opposite sides of the pinion-shaft which isturnable loosely through the pinion, a chamber in the pinion withinwhich the clutch-arms lie, the ends of said arms engaging the innerperiphery of the chamber to turn it when moved in one direction andreleasing it whenever moved in the opposite direction.

In witness whereof I have hereunto set my hand. I

FREDERICK E. SCHMITS.
